“…The spacings above 0.45 m (0.60 and 0.75 m) did not promote significant increases for variables of these hybrids. The values of the straw with ear weight corroborate those obtained by [16] that when evaluating the hybrid 'AG-1051', aimed at producing corn, reached values of 14.39 Mg ha The interaction between hybrids and spacing influence (p < 0.01) the weight of 1000 seeds (P 1000). The length of the spike (C), grain yield (PG) and mass cob (MSAB) were affected (p < 0.01) by treatment alone (Table 4).…”

One of the most important crop practices to obtain high grain and forage yields in maize is the correct management of the seeding density, because the plant stand can influence growth components, production and partitioning of photoassimilates. The objective of this study was to evaluate the growth and yield of corn cultivation at five spacings, using two hybrids. The experiment was installed at the experimental farm of the Federal University of Campina Grande, CCTA/UFCG, Campus de Pombal, located in the city of Santo Domingo-PB. The experimental design was a randomised complete block, in a factorial scheme, with the factors being five spacings and two hybrids, with four replications. The spacings were 0.15, 0.30, 0.45, 0.60 and 0.75 m between plants, and the two hybrids were 'AG-1051' and 'BR-106'. The following yield components were evaluated: ear weight with straw and without straw; weight of 1000 seeds, ear length and diameter, grain yield and mass of corn. The spacings of 0.30 and 0.45 m had the best results, corresponding to the population densities of 30,000 and 40,000 plants ha -1 , and the 'AG-1051' cultivar had the best performance, with an average yield of 13 t ha -1 , largely due to its better genetic load.

“…Moreover, in a study on the possible residual effect of swine biofertilizer, Santos et al (2011) reported there is a need for complementation of essential nutrients, especially N and K. Therefore, it is reasonable to assume that the combination of mineral and organic sources of nutrients has a positive effect on various crop yields.…”

ABSTRACT:Composting is a useful way of transforming livestock waste into organic fertilizer, which is proven to increase soil nutrient levels, and thus crop yield. Remains from production and slaughter of small ruminants can become a source of important elements for plant growth, such as N, after microorganism-driven decomposition.The aim of this investigation was to evaluate the effects of this compost on soil fertility and on the nutritional status and yield of the corn crop. The experiment was conducted in a Haplic Luvisol in a randomized block design with six treatments and five application rates of the organic compound in Mg ha -1 : 3 (half the standard rate), 6 (standard rate), 9 (one and a half times the standard rate), 12 (twice the standard rate), and 24 (four times the standard rate) and an additional treatment with mineral fertilizers (110, 50 e 30 kg ha -1 of N, P 2 O 5 and K 2 O, respectively), with four blocks. Evaluations were performed for two harvests of rainfed crops, measuring soil fertility, nutritional status, and grain yield. The compost increased P, K, Na and Zn values in the 0.00-0.20 m layer in relation of mineral fertilization in 616, 21, 114 and 90 % with rate 24 Mg ha -1 in second crop. Leaf N, Mg, and S contents, relative chlorophyll content, and the productivity of corn kernels increased in 27, 32, 36, 20 e 85 %, respectively, of low rate (3 Mg ha -1 ) to high rate (24 Mg ha -1 ) with of application of the compost. Corn yield was higher with application of organic compost in rate of 24 Mg ha -1 than mineral fertilizer combination in second crop.

“…Por apresentar demanda contínua durante todo o ano e elevada taxa de agregação de renda aos produtores, o cultivo do milho verde é uma atividade de interesse econômico ao produtor (Alves, 2004). O cultivo de milho verde ocorre em pequenas e médias propriedades (Santos et al, 2011) o que produz um aspecto importante para a região de seu cultivo, que é a geração de emprego e renda.…”

A cultura do milho verde apresenta importância econômica e social relevante para os pequenos e médios agricultores, como fonte de renda e alimento, tanto para alimentação humana como animal. Este estudo teve como objetivo avaliar o desempenho de cultivares comerciais de milho para consumo in natura nas condições edafoclimáticas de Jataí, região Sudoeste do Estado de Goiás nos períodos de safrinha e safra de verão. Os experimentos foram instalados em delineamento de blocos casualizados com quatro repetições e 10 cultivares. Foram avaliadas as características: altura de planta, altura inserção de espiga, diâmetro e comprimento de espigas, produtividade de espigas com palha e sem palha, produtividade comercial e teor de sólidos solúveis. Todas as cultivares avaliadas na safrinha apresentaram características para o consumo in natura na forma de milho verde, já para as cultivares cultivadas na safra a cultivar BM 840 foi a que apresentou maior produtividade de espigas para o consumo na forma de milho verde.
